The gamma-ray spectrum of 27th Ho166 was re-investigated by means of a three-crystal pair-spectrometer and coincidence techniques. Two new gamma rays with energies of 1747 plusmn 5 and 1825 plusmn 5 keV establish a new level at 1826 keV in Er166. The log ft value for the beta-decay to this state is 5.2-0,4+0.3 and suggests an allowed unhindered transition. Single particle assignments for this level are discussed.
